CAR-COU PLING.

SPECIFICATION forming part of Letters Patent No. 502,631, dated August1, 1893.

Application iiled March 30, 1893.

To a/ZZ whom tem/ay concern:

Be it known that we, CHARLES W. MCMIL# LEN and HOWARD F. MCMILLEN, bothresidents of New Castle, in the county of Lawrence and State ofPennsylvania, have invented certain new and useful Improvements inCar-Couplings; and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

Our invention relates to that class of railroad car-couplers, known asautomatic coupn 1ers, in which the cars are coupled when they cometogether without the necessity of a brakeman or other person goingbetween the same.

The object of the invention is to provide a novel coupler of the abovedescription which shall possess superior advantages with respect tosimplicity and efficiency in use.

The invention consists in` the novel construction and combinationofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a perspective view ofa railroad car with our improved coupler applied thereto. Fig. 2 is acentral longitudinal section of two couplers constructed in accordancewith our invention, coupled or connected together. Fig. 3 is aperspective view of the pivoted coupling arm detached; and Fig. 4 a planView of the same. g

In the said drawings the reference numeral l designates a portion ofanordinary freight' car, and 2 the drawhead connected with an ordinarydraw bar, (not shown.) This drawhead is formed with the ordinary flaringmouth to receive the usual coupling link 3, and at its front endisprovided or formed with a central beveled or curved lug 4, againstwhich the link strikes as it enters the drawhead, having a shoulder 5 atits rear end with which the coupling arm 6 engages. This coupling armconsists of a metal bar, pivoted on a rod 6a, extending transverselythrough lugs Serial No. 468,342. (No modell) 7, formed on the upperfront end of the drawhead, and is formed on the upper side of its freeend with a lug 8, with which is connected a vertical rod 9, connectedwith a crank 10, on a shaft 12, journaled in the end of the car. Thelower end of the coupling arm on each side is cut away on a curved line13, forming a lug 14, and just above this lug is formed with arearwardlyV extending iiange l5, and two outwardly extending iianges 16.

It will be noted that the top and bottom of the drawhead is completelyclosed with the exception of two aligned holes or apertures 17 and 18.In the lower hole 18, the free end of the coupling arm rests whendepressed, while the connecting rod 9, passes through the upper hole.Loosely mounted on this rod is a disk or annular plate'19, the object ofwhich `is to t over the hole 17, and prevent snow, rain and dirt fromentering the drawhead. This disk, as before stated, is loose on the rod,so that it will not move therewith, but always seat itself by gravity onthe draw- I head.

vbeveled or curved lug 4, and riding over the same. As the link passesover this lug it will strike and turn the coupling arm and when it haspassed the same, said arm will fall by gravity and engage with theshoulder on the rear of said lug. The link will now engage between theupper side of the lug 14 and the flanges 15 and 16, and the cars be thuscoupled together, the lug 4, holding the coupling arm in place.

To uncouple the cars the coupling arm is elevated by means of the shaft12 and its connections.

Having thus described our invention, what we claim is- Ina car couplerthe combination with the drawhead formed with a central beveled orcurved lug in its front end, and withaligned apertures in the top andbottom, of the pivoted gravity coupling arm, cut away on each side on acurved line at its free end, formed with rearwardly and outwardlyextending In testimony that we claim the foregoing as to flanges betweenwhich the coupling link is our own We have hereunto axed oursignaadapted to engage, and also formed with a tures in presence of twowitnesses.

lug. the vertical connecting rod connected 5 with said lug and'passingthrough the upper aperture in the drawhead, the disk loosely J mountedon said rod, and the opening shaft Witnesses: connected with said rod,substantially as de- J. A. ADDIS, scribed. JOHN S. TAGGART.
